Their concerns relate both to policing and driver behaviour. 73 per cent of people polled believe law enforcement do not have sufficient tools to identify marijuana-impaired drivers. 65 per cent of participants expect instances of impaired driving will go up when marijuana becomes legal.

This comes one day after the province said police will not have oral fluid screening devices in place by Oct. 17, the day of legalization. They expect to have at least 21 devices in use by the end of March.

Even with one less tool at their disposal, Winnipeg police say they will rely on their current roadside sobriety tests to spot cannabis-impaired drivers.

“We’ve been detecting drug-impaired drivers for years. This is nothing new to us,” traffic division inspector Gord Spado said.
